Create a PhysicsMask by specifying multiple bits to set (1).

public PhysicsMask(params int[] bitIndices)

int[]

Each value is the index of a single bit to set, not a mask of bits. An integer that holds a layer mask, such as the value of a LayerMask, is not converted here and is read as a bit index instead. For example, a layer mask with only layer 8 set has the value 256, which is read as bit index 256 and throws an exception, and a layer mask of 3 sets bit 3 rather than bits 0 and 1. To create a PhysicsMask from a layer mask, pass the LayerMask itself to PhysicsMask. If the layer mask is held in an integer, convert it first, for example .

Create a PhysicsMask from a LayerMask. A LayerMask is only 32-bits wide so the PhysicsMask will have the upper 32-bits set to zero.
